NBC NATIONAL NEWS — General Motors says they're recalling more than 4-thousand 2012 Chevrolet Sonic cars due to concern that some of the vehicles could be missing brake pads.

General Motors says they made the find during a routine warranty service check.

If you have one of these cars, you'll get a letter in the mail early next month.

You're supposed to bring that letter, and your car, to the dealer to get checked out.
